TRIPOLI/BENGHAZI - Crowds of joyful Libyans, some with tears in their eyes, parted with the legacy of Muammar Gaddafi's dictatorship on Saturday as they voted in the first free national election in 60 years. But in the eastern city of Benghazi, cradle of last year's uprising but where many now want more autonomy from the interim government in Tripoli, protesters stormed a handful of polling stations and publicly burned hundreds of ballot papers. Authorities also reported a case of gunmen preventing voters from entering polling stations in the eastern oil port town of Ras Lanuf, but said 94 percent of polling stations around the North African country were up and running normally. Libyans are choosing a 200-member assembly which will elect a prime minister and cabinet before laying the ground for full parliamentary elections next year under a new constitution. Candidates with Islamic agendas dominate the field of more than 3,700 hopefuls, suggesting Libya will be the next Arab Spring country - after Egypt and Tunisia - to see religious parties secure a grip on power. In Benghazi, protesters stormed a polling station just after voting started and set fire to hundreds of ballot slips in a public square in a bid to undermine the election's credibility. Witnesses said at least four polling stations had been hit in such attacks. One man was shot in the arm and taken to hospital with heavy bleeding after a stand-off between vote boycotters and those in favour of the elections. "There wasn't enough security at the station to stop the attackers," Nasser Zwela, 28, told Reuters, saying protesters armed with assault rifles had stormed one local polling station and shouted at everyone to stop voting. Yet in the capital Tripoli, voting was smooth. A loud cry of "Allahu akbar" ("God is greatest") went up inside one polling station there as voting began in a converted school building abuzz with the chatter of queueing locals. "I am a Libyan citizen in free Libya," said Mahmud Mohammed Al-Bizamti. "I came today to be able to vote in a democratic way. Today is like a wedding for us." Some voters struggled with procedures for casting their ballot. In one central Tripoli district, two women disappeared into a voting booth together before an election worker hurriedly explained they must vote alone.
